SHEET-STEEL KEG FOR WHITE LEAD.

No. 878,576. I

Specification of- Letters Patent. Application filed November 21.1906-Serial No. 344.419;

Patented Feb. 11, 1908.

Ohio, have invented a new and useful Improvement in Sheet-Steel Kegs forWhite Lead, of which the following is a specification.

My invention relates to improvements in sheet metal or steel kegs orvessels for holding, handling and shipping white lead or other extremelyheavy materials in packages or units of 25, 50 or 100 pounds, or thelike.

The object of my invention is to provide a sheet metal keg of asi1nple,-efficient, strong and durable construction, capable of beingcheaply manufactured and which, when filled with white lead or otherheavy material, may be safely handled in the usual manner without dangerof leakage or breakage, or of loosening or springing off the cover incase the heavy package should, in falling from a height strike upon itsside, edge or corner.

My invention consists in the means I employ to practically accomplishthis object or result, as herein shown or described and moreparticularly specified in the claims.

In the accompanying drawing, forming a part of this specification,Figure 1 is a side elevation of a sheet steel keg for white leadembodying my invention. Fig. 2 is a central vertical section. Fig. 3 isa top or plan view. .Fig. 4 is a detail side elevation, showing the bailear and cover-holding clip, and Fig. 5 is a detail cross section on line5-5 of Fig. 4:.

In my improved sheet metal keg the body of the vessel is composed of twoseamless bilged or barrel-shaped body. sections A and B, drawn orpressed to the required shape, the lower section, A, having an integralbottom a, and the upper section, B, having an inwardly and downwardlyturned curved flange b forming an annular friction seat wall for thecover D. And the two body sections A B have at their meeting ends,external or outwardly. projecting annular flanges 0, b folded togetherinto an external lock seam a uniting the two sections at the middle ofthe body of the barrel-shaped keg or vessel, the folded seam a unitingthe two sections also constituting an external annular strengthening ribto strengthen and stiffen the vessel at its median line. To furtherreinforce, strengthen and stiffen the flat integral botbrace and furthersupport the lower end of the lower section A of the body, it, isprovided with a supplemental bracing and supporting disk C, engaged andheld in place at its peripheryby an annular bead or enlargement (1 atthe lower end of the lower section A. The cover D has a deep countersinkD therein, forming an annular inside fitting friction seat wall orflange d, snugly fitting and engaging the annular depending flange bsurrounding the central opening B in the upper end of the upper sectionB. The cover D also has an outer parallel annular flange d surroundingand embracing the upper end of the upper section, and snugly fitting thesame.

The inner and outer flanges (1 d being united by a curved flange (Z andtogether forming an annular channel, U-shaped in cross section, snuglyembracing, inside and out, the upper end of the upper section with itsinwardly and downwardly curved flange, which flange gives such upper endof the upper section a corresponding inverted U- shape in cross section.The tight wedging fit cover thus serves not only as a closure for theopen mouth of the vessel, but also as an internal brace and as anexternal band or hoop to brace and bind, stiffen and strengthen theupper end of the upper body section. To hold the cover in its snug tightbraceacting and stiffening engagement with the upper end of the bodysection, and to prevent danger of the cover loosening or springing offwhen the vessel is subjected at any part to a heavy blow, the body isprovided with cover holding clips F F secured thereto by rivets f andwhich are hammered or clenched down over the upwardly projecting annularrim of the cover formed by its inner and outer annular flanges d al Theupper section of the body is preferably provided with external circularrecesses or shoulders I) to receive the lower ends f of the clips F, andthus afford additional strength and security to the attachment of theclips with the. body. The bail ears G have circular heads or lower ends9 also partially fitting in these recesses of the body, and these bailears are also furnished with longitudinally extending recesses g stampedtherein to fit and partially receive the lower ends of the cover holdingclips F. The rivets f extend through the cover holding clips and thebail ears G, so that tom head a of the vessel,andto internally the samerivet serves to attach both parts to the body. H is the bail, preferablyof wire, and having loops or eyes h which are inserted through suitableholes g in the bail ears.

I claim:

1. A sheet steel or metal keg for white lead, comprising two bilged orbarrel-shaped seamless sections, having outwardly proj ecting externalannular flanges at their meeting ends, folded together into a'seamuniting the two sections, the lower section having an integral bottom,the upper section being furnished at its upper end with an inwardly anddownwardly curved flange or roll, a cover having inner and. outerparallel flanges tightly fitting and embracing the flanged upper end ofthe upper section, a pair of cover holding clips, a pair of bail earsfitting over said clips, rivets extending through the bail ears andclips for securing the same to the upper body section, saidbodyhavingexternal recesses therein to receive the lower ends of the bail ears andclips, and the bail ears having longitudinal recesses fitting andembracing the lower ends of the clips, substantially as specified.

2. A sheet metal keg having a body provided at its upper or mouth endwith an inwardly and downwardly curved flange or roll, a cover havingthe inner and outer parallel flanges tightly fitting and embracing theflanged upper end of said body, a pair of cover holding chps, a pair ofbail ears fitting over said clips and rivets extending through the bailears and clips for securing the same to the body, said body havingexternal recesses therein to receive the lower ends of the bail ears andclips, and the bail ears havinglongitudinal recesses fitting andembracing the lower ends of the clips, substantially as specified.
